Subject: [PATCH 1/1] dt-bindings: fsl: convert m4if.txt and tigerp.txt to yaml format

Convert m4if.txt and tigerp.txt to yaml format. These just use reg to
indicate memory region.

Additional changes:
- Add compatible string fsl,imx51-aipstz.
- Add fsl,imx53-tigerp and fail back to fsl,imx51-tigerp
- Add compatible string fsl,imx7d-pcie-phy, which is not real phy and just
indicate a memory region.
